Specification of Letters. Patent.

Application filed November 17, 1913. Serial No. EA)1,3:39.v

a citizen of the United States, and a resident.

of Chambersburg, in the-county of Franklin and State of Pennsylvania,have invented certain new and useful Improvements in ConvertiblePresses, of which the following is a specification.

My invention relates to improvements in presses for forcing on orremoving from axles or shafts wheels, gears, couplings, etc, and theobject of my invention is to furnish a press of this character whichwill be adapted for use in connection with either an overhead travelingcrane, such as many shops are equipped with, or with a relatively lightremovable trolley carrying beam and hook trolleyfor use where atraveling crane is not at hand or when it is desired to operatethe pressindependently of such a crane.

/Vheel presses for my purposes asordinarily constructed comprise a fixedcylinder beam, a fixed end supporting beam, and a movable intermediateresistance beam which is located between the two first beams. Thecylinder'and end supporting beams are tied together by means of tie-barsat their upper and lower ends and the intermediate resistance beam isadjustably secured to these bars as may be'necessary for the workthat-the machine is to perform. In some cases a hook trolley, carried bythe upper tie-bar, is em ployed to carry the object to be operated uponby the press, in others the object is carried by a crane that may formpart of the equipment of the shop in which the press is installed. Ifthe press is to be used in connection with a trolley carried by theupper tie-bar it is usual, for the proper distribution of strength andstrains, to locate the upper and lower tie-bars and the axis of thecylinder carried by the'cylinder beam all in the same vertical plane. Ifthe press is to be used in connection with a shop crane the uppertie-bar as thus arranged will be found to be directly in the way of thehoist-- ing chain. To meet this difliculty it has been customary toconstruct the machine with movable tie-bars, each of which may beconstructed of a single or of a multiplicity of bars, which can beshifted from a vertical to an inclined planeas may be required for ahook trolley carried by the upper bar or bars or for use in connectionwith a travelerane.

In wheel presses of the so-called inclined type, such for instance asset forth in patent to Augustus Wood, No. 9%,98 January 18, 1910, it isnecessary when changing from a vertical to an inclined arrangement ofthe tie-bars or vice-versa, to remove and shift the tie-bars, and asthey are of necessity heavy, considerable trouble is had in effectingthe transfer particularly if the overhead crane, which mi 'ht beused inconnection with this work, be temporarily out i of service.

My present machine has been designed so that there are no very heavyparts to move to adapt it for use either in connection with the usualtraveling crane of the shop or with a hook trolley carried upon a beamrunning lengthwise of and carried by the press.

It comprises the usual cylinder and end supporting beam, a movableintermediate resistance beam, all of which are inclined from thevertical and secured by permanent tie-bars, and of a light track, forcarrying a hook trolley, which can be removed from or placed upon thebeams at any time in a few minutes and without the aid of any heavylifting mechanism.

My invention consists, further, in certain details of construction whichwill be hereinafter fully pointed out. v

In the accompanying drawings which form part of this specification, and1n which similar letters of reference indicate similar Fig. 5, an endelevation of the end supporting beam. Fig. 6, a side elevation of a plugthat may be used in certain cases instead of the sleeve 13.

1. is the cylinder beam and 2 the end supporting beam. The cylinder beamcarries the usual hydraulic cylinder and piston which are so well knownthat detailed description of them, or the means for admitting orexhausting the actuating fluid, will be unnecessary. Both of these beamsare stationary, are inclined from the vertical as shown and are tiedtogether by fixed tierods 3 and 4, the former secured to the beams attheir tops, to the rear of a vertical plane passing through thelongitudinal center of the cylinder in the cylinder beam, the lattersecured to the beams at their lower ends forward of said vertical plane.The said bars and the center of the cylinder being on a true diagonalline with the center of pressure may be used in conjunction with anoverhead crane or with a relatively light carrier beam 5 with itstrolley 6 and hooks 7. This carrier beam to be removed when an overheadcrane is employed. The beam 5 is removably carried by the end beams l2and as it serves only to carry the trolley 6 and the work that may becarried by the hooks of this trolley it can be so light as to be easilyand quickly removed or replaced by hand.

In order to retain its stability, the interniecliateinovable resistancebeam 8 is provided with an outrigger 9 and Wheel 10 which is carriedupon a permanent track 11. At its front side the beam 8 is furnishedwith a wheel 12 which runs on the top of the tie-bar i and through thesetwo wheels this beam may easily be moved back and forth as may benecessary in performing different operations.

16 are the usual keys for locking the inter mediate beam 8 to thetie-bars.

In this convertible press it is not neces sary to use the usual soleplate the tiebars, being never moved, retain the cylinder and resistancebeams in proper alinement when a suitable foundation is furnished.

in order that the sleeve 13, which in the vertical axis press is usuallysuspended from the upper tie-bar, may be operative under any condition,I suspend it from a jib or davit crane 14 pivotally carried by thecylinder beam 1. The sleeve 13 may be demounted from the crane 1% and aplug 15 substituted for it in order to operate upon a wheel pulley orcoupling the hub of which is flush with the aXle or shaft. It will beobvious that other forms of tools or appliances may be supported by thiscrane which is so carried that it can be used without interfering in anyway with the convertibility of the press.

Having thus described my invention I claim as new and desire to secureby Letters Patent 1. In a wheel press, in combination, a fixed cylinderbeam, a fixed end supporting beam, and a movable resistance beam all sorearwardly inclined that their upper ends are to the rear of and theirlower ends in front of a vertical plane passing through the longitudinalcenter of the press, a tie-bar permanently secured to the upper ends ofsaid cylinder and end beams, a tie-bar permanently secured to theforward lower ends of said beams, said tie-bars movably supporting saicresistance beam, and a light removable beam carried by the upper ends ofsaid cylinder and end beams in a vertical plane passing through thelongitudinal center of the press.

In a wheel press, in combination, a fixed cylinder beam, a fixed endsupporting beam, both so rearwardly inclined that their upper ends areto the rear of and their lower ends to the front of a vertical planepassing through the longitudinal center of the press, tie-barspermanently secured to the upper ends and to the forward lower ends ofsaid cylinder and end beams, a movable resistance beam inclinedsimilarly to said cylinder and end beams carried by said tie bars andfurnished with an extension to the rear, a roller carried by saidextension, a track upon which said roller runs, means for locking saidmovable beam to said tie-bars, and a light removable trolley carryingbeam carried by the upper ends of said cylinder and end beams in avertical plane passing through the longitudinal center of the press.
